# install on linux Ubuntu 18.04

Hi,

I run into problems when installing itensor on Linux(Ubuntu 18.04 ). Here is the error message after running the make file:

Makefile:2: /home/essa/itensor/thisdir.mk: No such file or directory
make: *** No rule to make target '/home/essa/itensor/this
dir.mk'. Stop.

Do you have any idea what went wrong?

Thanks

Which version of ITensor are you using? If you are using git, could you run git status to see what branch you are on?

It looks like maybe your Makefile has been modified, since it should search for this_dir.mk, not thisdir.mk.

Hi, could you try doing "make clean" at the top level of your itensor folder then do "make" again? If you then get the same error, can you please do "ls" and see if there is a file called "this_dir.mk" and also please tell us what is inside this file? Thank you -

Miles

hi,
Thanks for the reply. I followed your instructions, but I still have the same problem.
by the way there is no file called "this_dir.mk" .
